[Bluej-discuss] Failure to launch BlueJ

[M.Edwards]

I have a student who is unable to launch BlueJ on a Windows XP
Professional machine. The splash screen appears and then vanishes and
nothing further happens. The bluej-debuglog.txt file is shown below.
Does anyone have any ideas/suggestions as to what the problem is and how
it might be resolved? (I'm wondering if it is to do with the look and
feel and if bluej.lookAndFeel=crossplatform in bluej.defs might help?)

Thank you.
